I am starting with a new building. It has a pressed wood floor OSD (or something like that). I am going to put a sheet of heavy duty vinyl flooring over it to protect it from moisture. the question is, should I paint it before installing the vinyl flooring? I have the paint (outdoor latex), but I want to do it right THIS TIME. The building itself is a steel building already "painted" or whatever you do to steel buildings. This is just the floor inside that will be under vinyl.
